Hot Rod Charlie worked six furlongs over the Keeneland main track Oct. 29 in company with Roses N Gold ahead of a start in the Nov. 5 Longines Breeders' Cup Classic (G1) back at the Lexington oval.
With Tyler Gaffalione aboard, Hot Rod Charlie started four lengths back from his workmate, cut the deficit in half by the quarter pole, and cruised past at the eighth pole en route to a time of 1:12 4/5.
"He looked good and I got him in 1:12 and 4," O'Neill said.
In Hot Rod Charlie's only start at Keeneland, he was second to champion Essential Quality in the 2020 TVG Breeders' Cup Juvenile Presented by Thoroughbred Aftercare Alliance (G1) at 94-1 odds.
The Roadrunner Racing, Boat Racing, Strauss Bros Racing, and Gainesway Thoroughbreds-owned Oxbow colt was fourth in last year's Breeders' Cup Classic at Del Mar.
